MACHINE FOR PUNCHING AND FORMING CALKS 0N HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 494,623, dated April 4,1893.

Application filed October 20, 1892.

To all whom it may concern:

Be it known that I, WILLIAM NELSON BRIGKEY, a citizen of the UnitedStates, residing at Morrillton, in the countyof Conway and State ofArkansas, have invented certain new and useful Improvements in Machinesfor Punching and Forming Oalks on Horseshoes; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

My present invention relates to a novel machine or implement by whichcalks can be formed on horse shoes and the holes punched therein toreceive the nails by which the shoe is fastened on the animals foot.

The object of my present improvement is, first, to provide simple andeffective means whereby the calks can be quickly, easily and accuratelyformed on the horse shoe; second to quickly punch or force thenail-holes in the shoe and without requiring the shoe to be reheatedafter the calks have been formed and prior to the punching of the holes;thirdly to prevent the punch-die from becoming over heated by theprovision of means which serves to cool the die each time it passesthrough the hot metal of the shoe; and finally to simplify cient andreliable in operation.

With these and other ends in View, the first part of my inventionconsists in the combination with a vertical upright or standard, of apivoted clamp -bar which is arranged alongside of the standard and has adie or anhead or plate pivoted to the fixed standard and adapted tocarry a die in a holder which operates to bend the metal of the shoe toform a calk thereon, and a lever fulcrumed to a fixed support andbearing against the pivoted clamp and anvil bar to hold the latter inposition to clamp the work between itself and the fixed standard.

The second part of my invention consists in the novel means for punchingthe holes in the shoe and keeping the punch-die cool,

which means consists of a reciprocating die Serial No. 449,501- (Nomodel.)

guided in a fixed guide on the frame, the lever, a link pivoted at itsends to the die and the lever, and a tank adapted to contain wafor orother liquid and arranged in the bed of the machine to receive the punchdie after the same passes through the hot metal of the shoe, whereby thereciprocating die is immersed in water or liquid at each stroke thereof.And finally the invention consistsin the peculiar construction andarrangement of parts which will be hereinafter fully described andpointed out in the claims.

The invention is fully illustrated in the accompanying drawings, forminga part of this specification, and in which;

Figure 1 is a perspective View of my improved calk-bending and punchingimple ment or machine. Fig. 2 is a vertical sectional View thereof. Fig.3 is a detail onlarged view of a part of the calk-forming devices, moreclearly showing the form thereof on an enlarged scale.

Like letters of reference denote corresponding parts in the severalfigures of the drawings, referring to which:- g

Adesignates the bed of my improved calkforming and punching machineespecially adapted for use by blacksmiths and others in manipulatingshoe-blanks to be fitted to the feet of horses and other animals. Onthis bed is erected the supporting frame B, and the Vertical standard orupright O, which parts are rigidly and firmly secured to the bed andconnected together by the horizontal struts or bars 0, c, which alsoserve as the guides for the free end of the clamp and anvil bar D. Thisbar D is arranged in a vertical position alongside of and close to thefixed upright or standard 0, and the upper end of this anvil and clampbar is fitted and guided between the horizontal bars 0 0 while the lowerend of said vertical bar D is pivoted to the bedA of the machine. Theupper free end of the vertical pivoted bar D is adapted to bear orimpinge against the front face of the vertical fixed standard 0, inorder to hold or clamp the work between said b'ar D and the standard O;and normally this free end of the vertical pivoted bar is forced orthrown away from the fixed standard 0 by means of the spring E which isinterposed between the bar and standard or otherwise connected in any roing plate to be turned at an angle to the length of the standard 0 or tobe raised in line therewith. This bending pivoted plate F has its upperend provided with a handle 9 by which the plate can be readily turned,and on the lower central part of the plate is bolted or otherwisesecured a die holder H, having its lower end provided with a notch orsocket adapted to receive a die H of the proper size and shape to formthe calk on a shoe. The

upper end of the vertical pivoted bar D is forked or recessed at 2' toenable the same to receive a corresponding die I, and between these dies11, I, the metal is bent to form the calk on the shoe.

The dies may be of different sizes to adapt them to bend the calkson-shoes of different sizes, and any desired set of dies can be readilyfitted in the sockets of the die holder and the end of the clamp andanvil bar D. On the upright fixed frame 13 of the machine is rigidlysecured a vertical hollow guide J, and through the passage in this guideworks a reciprocating punching die K, the lower end of which is adaptedto pass through a perforation 7c in the bed A.

Immediately below the guide and the reciprocatin g punch die, I providea liquid holding tank L which is suitably formed or secured in the bed Aof the machine, and when the reciprocating punch passes through theperforation Is it is immersed directly in the liquid contained in thetank L so that the punch is cooled by the direct application of waterthereto after each time it passes through the heated metal.

The reciprocating punch is operated by means of alever M which isfulcrumed at an intermediate point of its length to the frame B of themachine, as at m, and to this lever is pivotally connected one end of alink N which has its other end connected directly to the punch, asshown. This lever M is so arranged that its inner end is adapted to beardirectly on the vertical pivoted bar D in or- 5 5 der to force the sameinward to hold the work between its free end and the fixed standard 0;and this lever M thus serves a two-fold purpose, 2'. 6., to reciprocatethe punch and to force the pivoted bar into position to hold the workbetween said bar and the standard.

plate, and the shoe-blank heated, the latter is fitted between thepivoted bar and the fixed standard so that one end thereof lies betweenthe two dies. The lever M is now operated to force the end of the bartightly against the shoe-blank, and the pivoted plate now turned atright angles to the standard so as to bend the end of the shoe blank andform the calk on the same. The lever is then operated to release thepivoted bar and blank, the latter turned so that its other end isbetween the dies, the lever again operated to clamp the pivoted bar onthe blank, and finallythe pivoted die-plate is turned to form the othercalk. The shoe-blank is now removed and placed in position beneath thepunch, and the latter is operated by means of the lever so as to punchthe holes in the shoe-blank to receive the nails. At each operation ofthe punch, it enters the water in the tank and is thus kept in a coolcondition.

By means of this machine or implement the shoe-blank can have its calksformed thereon and the holes punched therein without reheating theblank,which is a very great advantage as itenables the workman toquickly finish the shoe.

The device is simple and durable in construction, reliable and effectivein service, and cheap of manufacture.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
